Great numbers.

I got 390rwhp and 430rwtq out of my LS1 with stock heads. My cam is a 228/232 .588/.574 113LSA


I can't wait for my new cam to go in, hopefully I can brag about my cam only numbers as well. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />


Again great numbers.

how much surging does this cam have, and are their any tuning recommendations to cure it?

I found that this cam pulls very very hard from 3000-to 6600 RPM's (M6). On stock tuning mild head work, Dynatech headers, no cats Random Tech catback, LS6 intake, I made 409.6 RWHP and 378.8 RWTQ at 15-1 A/F and with Fiskes 17x11's on the rear. (We dynoed my car with stock wheels and gained 15 HP in the past) The idle is set at 1100, which I believe to be a little high. I am still having a problem with it searching for an idle, which really makes me upset! It falls to 200 rpm's, and goes up to 1500 rpm's. Thats my only concern. I hope we can fix that through tuning...if anyone has any ideas how to do it. We worked on it the night we installed the cam.

They should be in the 25-35 range. If they are much higher than this, take your TB off and drill the hole in the TB blade one size bigger. This should help with the surging idle. Good luck!

Thanks for the info Jason!
